Positive Displacement (PD) Meter
Master Meter’s design engineer responsible for crafting our MMPD Oscillating Piston meter is a lifetime member of the American Water Works Association, and the recipient of their coveted George Anderson Award for his leadership on the AWWA Standards Committee for Water Meters.
Using the very latest in R&D science, tooling, and fluid dynamics optimization technology, our PD meter is the most advanced traditional positive displacement meter available today. We’ve pushed the envelope for low flow / leak measurement, reduced the noise commonly associated with PD meters, and extended the longevity of the accuracy curve.
"A trifecta in modern positive displacement metrology"
Traditional residential or homes with larger landscaping requirements 5/8” – 1”.
Master Meter’s MMPD line exceeds the ANSI/AWWA C700 standard.
The Oscillating Piston (OP) chamber volumetrically fills and empties water, known as “positive displacement” (PD).
Verified through rigorous accelerated lifecycle testing by the independent Utah Water Research Laboratory.
Able to accurately record micro flow at ⅛” GPM to help notify and mitigate leaks.
The MMPD Positive Displacement meter works with all Master Meter and competitor AMR/AMI platforms.
The MMPD is designed to shift harmonics outside of the meter’s flow range to ensure quiet performance.
Advanced computerized modeling helps retains accuracy through greater usage and time.
The MMPD is an excellent alternative to the multi-jet measurement standard.
